Patented Nov. 23, 1937 DELIVERY MECHANISM FOR PRINTING MACHINES Josephll. Meyer, Jackson Heights, hi. Y., as'slgnor, by mesne assignments, to R. Hoe & 00., Inc., New York, N. Y., a corporation of New York Application November 15, 1933, Serial No. 698,083 19 claims. (CI. 93-93) This invention relates to certain improvements in delivery mechanisms for printing machines and more particularly to a mechanism for dividing or arranging the product of such a machine in evenly divided sets to facilitate the counting.

of same.

Among the objects of this invention, one is to provide a delivery mechanism which has a means for gripping each product as it is released from the folder of a printing machine and which is adapted to maintain said grip until the product is about to be ejected.

Another object is to provide a means whereby certain gripping members are periodically opened somewhat in advance of their regular order of opening and to provide a means to eject the product from the grippers at these periods. 7

In general, the structure involved in this invention comprises a rotatable cylinder having a plurality of evenly spaced ipper fingers mounted therein, said fingers having a gripper portion projecting beyond the surface of the cylinder and adapted to be moved when in engagement with the product of a printing machine or other similar machine, to grip and advance same to a normal y positioned stop, whereupon the grip is released and the product is ejected. A predetermined number of productsare ejected in this manner and deposited upon a conveyor in evenly spaced relation. After the desired number of products have been deposited in this manner, an auxiliary stop and gripper release mechanism is then actuated which is adapted to release and eject one product somewhat in advance of the normal release and ejecting position, to cause said latter product to project beyond the edge surface of the evenly spaced products when deposited upon the conveyor. In this manner, the products will be divided into sections, with an equal numher of products in each sectionand with one projecting product in each section to mark same.

With the above and other objects not specifically referred to in view, the invention consists in certainnovel parts, arrangements and, combinations which will be fully described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto annexed. I

In the drawings which show a preferred embodiment of the invention:

. Figure 1 is a vertical sectional viewtaken on the line I 2 of Figure 3, showing a cross section through the cylinder with-the gripper actuating and ejecting mechanism shown in normal operwhich the product is released from the press folder and a conveyor to receive same;

Figure 2 is a view similar to Figure l but showing the parts in a position at the time one product is ejected in advance of the normal order of ejection; and

Figure 3 is an elevational view taken in the di- I rection of the arrow 3 of Figure 1, with parts broken away.

Referring now to the details of construction, a cylinder II .is rotatably mounted in bearings l2 which are supported by side frames l3, only one of which is shown, and is driven in any suitable manner.

Above said cylinder H, a suitable guide mechanism I4 is provided through which the product of a printing press folder is adapted to pass, and which guides said product to align same with a gripping portion of a gripping mechanism to be hereinafter described.

.Below said cylinder II, a suitable conveyor I! is provided, upon which the product is deposited after it is ejected from the gripper mechanism.

Said gripper mechanism comprises a plurality. of fingers l6 having supporting lugs I! seemed thereto and fixed to shafts it, which shafts l8 are suitably mounted in end walls.|9 of said cylinder. The ends 2| of the gripper fingers l6 extend outward through openings 22 in the circumferential wall Ila of the cylinder and are bent inward to provide a gripper portion for same.

Arms 23, fixed to the ends of shafts l8, as shown in Figure 3, have cam rollers 24 mounted on the ends thereof, which rollers ride over the cam surface 25 of a stationary cam 26, bolted to the frame l3.

Fixed stop arms 21, are arranged to project into the path of the moving product when in engagement with the gripper fingers and may be mounted in any convenient manner. As shown in the drawings. each fixed stop comprises a bar mounted in a bracket 28, with said bracket se-.

upper end of said bar is curved and extends into a recess 3| provided in the circumferential wall Ila.

As thus far described the mechanism will function in the-following manner.

The product P, Figure 1, passes from the press folder through theguide mechanism It and ap-- proaches the cylinder ll just as the gripper portion 2| of the gripper fingers it are closing in on the surface of the cylinder l I, whereby said product is clamped between the finger and the cylint er Surface and moved therewith until the stops cured to a rod 29 mounted in the frames l3. The

llarereached. Justpriortotheengagementof the product with said stops, the gripping tension of the finger l isreleased, which thus permits in the same manner to pick up and release each product, and since the fingers are equally spaced around the cylinder, the products will be elected therefrom and deposited on the conveyor IS in I substantially equally spaced relation.

The means provided for counting the products comprises a mechanism which is adapted to eject one of every predetermined number of products, somewhat in advance of the normal order of ejection, and thereby cause same to extend out from those products on the conveyor which were ejected in their normal order. For example, let it be considered that every twenty-fifth product is to extend beyond theedge of the evenly spaced run of products deposited on the conveyor. This extended product would then function as a marker or guide'to simplify the counting of the products.

The mechanism involved in the latter operation consists of movable stop members 32, each having an arm 33 secured to a rock shaft 34 and a forwardly disposed extension 35, which is adapted to lie within a groove 3| of the cylinder wall Ila, out of the path of the gripped product, when the products are being run oil. in normal order or evenly spaced relation.

A cam shoe 38 is pivotally mounted at 31 within a cavity 38, in'the' stationary cam 16, and has one cam surface 3!.

A rocker lever ll is secured to the rock shaft 14 and has a roller 42 mounted on one arm thereof. A turnbuckle It has one end connected to another arm of said rocker lever 4| at H and its other end connected to the cam shoe 36 at 45. A rotatable cam I is mounted on a driven shaft 41, which shaft is carried inbearings in the frame l3, and is provided with a cam surface ll upon which the roller 42 rides.

During the normal run of said products, the parts of the mechanism'are positioned as shown in Figure 1, with the movable stop 32 and the cam shoe 38 positioned in an inoperative location. When the raisedportion 49 on the cam 48 engages the roller 42, the shaft ll is rocked, which rocking motion swings the extensionv IS on the movable stop 32, downward into the path of the product, and also causes the cam shoe 3' to be moved downward to present its cam surface to the appreaching cam roller 24. A new cam surface and a new stop at the edge II of the extension 32, is

thus momentarily provided to release and elect the product somewhat in advance of 'the normal order of ejection. The cam roller 42 then moves.

ofl the raised cam portion 49 and the rocker lever ll is rocked, which movement will cause the movable stop 32 and the cam shoe 3 to be moved to their inoperative position as shown in Figure 1. f

Itistobeunderstoodthatboth thecamroller I! and the cam rollers 24 will be maintained'in engagement with their respective cam surfaces II and II by any suitable means such as springs movable stop 32, are important improvements in a,ooo, aso A connection with counting mechanisms of this character.

While the invention has been shown and described in its preferred form, 'it will be understood-that certain changes and variations may be made in the specific structure provided for carrying out the invention without however departing from the spirit of the invention as defined in the appended claims.
